Dropbox is a cloud based program that keeps your files safe, synced, and easy to share. You save files on your computer, then access them on the fly from anywhere. Everything you keep in Dropbox is synced automatically to all your devices.
Why you need Dropbox: Having an online business is just that, most of your clients you will never meet face to face. This being said, you will need to have a space where you can keep documents, images, products and much more that is shared. The best thing about Dropbox is that it keeps you mobile as you can edit and share files on the fly from their app. For those starting their business, Dropbox has a free version and they give you up to 2GB of storage. The paid version starts at $9.95 a month for the personal plan which includes 1TB of space.
